Nordic-Baltic Hydrogen Corridor

The Nordic Baltic Hydrogen Corridor (NBHC) is an international project involving the construction of major hydrogen transmission infrastructure connecting Finland, Estonia, Latvia, Lithuania, Poland and Germany. The project is being implemented jointly by the transmission system operators from the following countries:


The project aims is to create a new cross-border corridor from Finland, across the Baltic States and Poland, to Germany. The completion of the NBHC will unlock the significant hydrogen potential of the eastern Baltic Sea region and ensure access to stable supply of renewable and low-carbon hydrogen for the countries through which the transmission infrastructure will be routed.

Access to low-carbon hydrogen is set to strengthen the Baltic region’s energy security, reduce dependence on imported fossil fuels and play a significant role in the decarbonisation of industry in the countries located along the corridor, including Poland. The project is also expected to contribute to the achievement of the European Union’s ambitious climate goals, relying on the decarbonisation of economies based on stable sources of renewable and low-carbon energy located within EU and NATO member states.  When combined with geographical proximity, this will enhance the security of energy supply.

The project is firmly aligned with the EU hydrogen strategy and REPowerEU plan. In addition, the Nordic-Baltic Hydrogen Corridor will support several regional and EU climate objectives, such as the EU Green Deal and Fit for 55 package.

PCI  
The Nordic Baltic Hydrogen Corridor has been included for the second time in the list of Projects of Common Interest (PCI) under the BEMIP Hydrogen initiative aimed at developing interconnections in the Baltic States’ energy market.

EU co-financing
The project promoters are conducting detailed technical, economic and financial analyses. This work was granted approx. EUR 6.8 million from the Connecting Europe Facility (CEF).

Project status
Given the complexity of the project, the partners have undertaken coordinated and proactive measures to ensure its success. A cooperation agreement for the joint implementation of the project was signed in December 2022.

Following the tender process, GAZ-SYSTEM and the European partners, signed an agreement for the preparation of a pre-feasibility study for the corridor. The work was completed in early July 2024. The study defined key project parameters, comprising technical, legal, organisational and economic aspects, and provides the basis for developing a roadmap for further project implementation.

Results of the pre-feasibility study
Analyses have shown that the Scandinavian and Baltic Sea region has significant potential for renewable hydrogen production. By 2040, it will be possible to produce approx. 27.1 million tonnes of hydrogen annually from offshore and onshore wind power and solar energy.  This creates favourable conditions for the development of the hydrogen market and its export to the mainland Europe, which is what the NBHC project is designed to facilitate.

It is estimated that by 2040, the corridor will allow annual cross-border transmission of up to 2.7 million tonnes of renewable hydrogen. The pre-feasibility study has confirmed that the NBHC may become one of the first operational cross-border hydrogen pipelines in Europe. The proposed infrastructure comprises an approx. 2,500 km long pipeline with a diameter of approx. 1,200 mm and featuring several compressor stations.

Feasibility study phase 
Based on the conclusions drawn from the analyses made during the pre-feasibility study phase, in the second half of 2024 the partners of the Nordic-Baltic Hydrogen Corridor moved on to the feasibility study, which includes detailed technical, economic and commercial analyses. 

Further steps
The results of these analyses will determine the next project stages and the prospects for the construction of a new cross-border hydrogen corridor.
